QR codes are everywhere. From menus in restaurants to marketing posters and payment portals, they have become a quick and convenient way to access information. With a simple scan using a smartphone, you’re instantly connected to websites, services, or promotional content. However, this convenience comes with risks, and the increased use of QR codes has caught the attention of cyber criminals.
The Rise of Malicious QR Code Scams
The growing popularity of QR codes has led to a rise in malicious activity known as “QRishing” — QR code phishing. In these scams, cyber criminals create fake QR codes that link to dangerous websites or trigger unwanted downloads. Because QR codes are just a series of seemingly random black-and-white patterns, it’s impossible to determine what they contain simply by looking at them. This gives criminals the perfect opportunity to deceive users, tricking them into scanning codes that can steal data or infect devices with malware.
For businesses and individuals alike, this can be a costly mistake. A malicious QR code could grant hackers access to sensitive information, compromise your device, or redirect you to counterfeit websites designed to steal your credentials.
How to Safeguard Your Business from QR Code Threats
Although QR codes can be risky, they don’t have to be avoided entirely. There are several ways businesses can mitigate these risks while still benefiting from the convenience they offer:
Educate Employees About QR Code Risks: Training your staff to recognise the dangers associated with QR codes is a crucial first step. They should be cautious when scanning codes, especially if they appear in unexpected locations or are not from a trusted source.
Use a QR Code Scanner with Previews: Encourage the use of QR code scanning apps that show a preview of the URL before opening it. This allows employees to verify that the link is legitimate and not a malicious site before proceeding.
Generate and Monitor Your QR Codes Securely If your business uses QR codes for marketing or operations, generate them through trusted and secure platforms. Regularly review and monitor your QR codes to ensure they haven’t been tampered with, and keep an eye on the websites they link to.
Implement Strong Cyber Security Defences Ensure your devices and network have up-to-date security software to detect and block malware. A robust cyber security strategy will reduce the risk of infection from malicious links and downloads.
